I recommend the thundermax with the auto tune. I have been running one for sometime now on my 07 dyna streetbob. I tried a few different programs found one that worked well. Iset the mixtures at 13:1 set and forget .I also run a type R hypo charger and a 2 into 1 supertrapp exhaust system. You will find the guys at zippers performance great to deal with if you have any concerns. I ran my bike on the dyno a few weeks ago for my own piece of mind and found it spot on as set 13:1 all through the range. It ran 77 hp and 88 ftlb of torque. It also fixed all the exhaust popping when backing off and running down. So happy just bought another one for my wifes bike.
A glowing report, they never seem to end for TMAT. What supertrap exhaust are you running? Haven't found any in Aus for 07's yet. Any photos? Sounds like you got your ride right?
I'm using a supertrap 2 into 1 with a 4 inch megaphoneand a race end cap installed .This has changed the note completly and is much quieter than the s&s mufflers I originally had fitted. I tracked down the exhaust system in Adelaide at SHOW AND GO motorcycles they had them in stock for 07 models.
